Systems and methods disclosed herein relate to generation and use of enhanced cross-layer metadata for a quality of experience (QoE) awareness mechanism within a network (e.g., wireless) device (e.g., user equipment (UE)). Examples of related mechanisms include a link selection mechanism, a link differentiation mechanism, a traffic or packet prioritization mechanism, and a packet queuing mechanism. A device may be understood according to a functional layer at the device used to communicate over a network. The QoE-based metadata may be transmitted in a southern (layer-down) direction to enable decisions at layers in the southern direction. Similarly, lower layer metadata may be communicated in a northbound (layer-up) direction to enable decisions at layers in the northbound direction. Various novel aspects of the type, generation, transmission, and temporal correlation of such enhanced metadata for QoE-aware environments are discussed.

The present invention discloses a traffic scheduling method and system based on dynamic priority. Specifically, the method comprises the following steps: the sending end calculates the remaining time and priority of each flow based on the SDN network status information; the intelligent decision-making layer server uses the MADDPG-Q algorithm to optimize the queue threshold to obtain a centralized training model; the control layer SDN controller reports the network status information to the decision-making layer server for model training and then transmits it to the switch; the forwarding layer programmable switch obtains multi-level feedback queue thresholds through the model and local information, assigns different priority queues to flows of different priorities, and completes flow priority scheduling; at the same time, data packets of different packet priorities in the same flow priority interval queue are sorted, and the position of the data packet in the queue is adjusted when the flow priority changes, thereby realizing dynamic priority queue scheduling. The present invention reduces the system's average flow completion time and can better adapt to complex distributed network applications.

The invention belongs to the technical field of wireless communication, and particularly relates to a self-adaptive backoff method based on emergency degree and channel load volatility. According to the method, the survival time constraint of the data packet, the same-priority differentiation demand and the dynamic change characteristic of the channel load are comprehensively considered. By sensing the time emergency degree of a data packet, shorter back-off time is allocated to the data packet which is close to timeout, and meanwhile, differential control in the same priority is realized; the backoff strategy is flexibly adjusted in a dynamic environment by monitoring the channel load fluctuation condition. The multi-dimension (data packet priority, channel occupancy rate, data packet emergency degree and channel load volatility) adaptive mechanism can reduce the system time delay and packet loss rate, improve the channel utilization rate and the system throughput, and enhance the fairness and differentiated service effect among data with different priorities while ensuring the high-priority data transmission performance.

Systems, methods, devices, and machine-readable media for improved communication between a software defined radio front end device and a network based computing device are disclosed in some examples.

In other examples, the RF front end device can prefer samples corresponding to certain data types over other data types.
